A mysterious woman, her nails painted with vibrant acrylics, entices her brother in a dimly lit room. She slowly strokes his throbbing cock, her long nails gently grazing his sensitive skin. With a sultry smile, she leans in, her tongue flicking across the tip, tasting the pre-cum. She takes him deep into her mouth, her acrylic nails pressing into his thighs, guiding his hips to thrust deeper. She expertly works his balls, pressing them gently with her nails, feeling them tighten as he nears climax. With a final, hard suck, she draws out his hot load, milking every drop.
